Otherwise tanks could just bypass queues (as it's quick for them) and switch to a non tank on entry in to the duty.
Well, someone would have to tank.

Someone that tries to *cheat* by queuing as tank then swapping to DPS demanding someone else swap to compensate, is going to get kicked. You could introduce a limit of "only allow swapping when the party is less than full".

Being able to freely switch between roles would be fantastic: if you get into a trial and someone else picked the same tank, can just alt over immediately instead of feeling bad about the overlapping SiO, or lack thereof.
